CodeIgniter框架学习笔记


1.安装所需库: gcc openssl-devel zlib-devel pcre-devel

编译安装方式：
解压**.tar.gz包
cd **目录下
./configure
make
make install

注： /opt/nginx/sbin/nginx -V 查看安装nginx时的编译选项，

从而查看安装的模块

2.下载 安装nginx
http://nginx.org/

3.配置nginx
/opt/nginx/conf/nginx.conf

}
}

}

}

location / {
if (!-e $request_filename) {
rewrite ^/(.*)$ /index.php/$1 last;
}

location ~ /index.php {
set $path_info "";
set $real_script_name $fastcgi_script_name;

}
}

fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
}
修改conf重启nginx /opt/nginx/sbin/nginx -s reload
local.cn 模拟域名设置
vi /etc/hosts加入
127.0.0.1 localhost local.cn


使用SQLite

1.安装SQLite

a.http://www.sqlite.org 下载编译安装

b.sqlite数据库管理

参看http://www.cnblogs.com/frankliiu-java/archive/2010/05/18/1738144.html


c.PHP / PDO / SQLite3 Example
参看http://www.if-not-true-then-false.com/2012/php-pdo-sqlite3-example/


2.CodeIgniter中数据库配置

a.查看所用CI sytem/croe下是否有pdo的driver

b.config/database.php进行数据库配置 参看http://codeigniter.org.cn

3.
